Abstract
Recently, light traps usinglight-emitting diode(LED) lightshave been applied to monitor or control insect pests. The oriental armyworm, Mythimna separataWalker, is an important insect pest that has caused damage to several cereal crops, including corn, wheatand rice. The present study aimsto seek out a sensitive wavelength causing high phototactic response in M. separata. The study evaluated the phototactic responsesofM. separata mothsto several LED lights of different wavelengths and luminance intensities under laboratory condition. Results showed that green (520 nm) LED light resulted in significant phototactic response of M. separata moths compared to LED lights of other wavelengths. Additionally, the highest attraction rate of the moths to green LED light appeared in luminance intensity group of 200 lux compared to the other intensities groups. Experiments under optimum conditions based on the above experiments revealed that the green LED light exhibited the strongest attraction rate (64.44%) among all experimental groups. An experiment performed in a net cage also showed that green LED light resulted in the highest phototactic response of M. separata moths, 1.7 times more than a commercial black light used as control. These findings clearly demonstrate that M. separata moths have a high sensitivity to the green LED light. Therefore, a light trap equipped with green LED light could be useful for monitoring and controlling M. separata moths.
